The midterm will be held Thursday, Oct 21, 2004.
Topics
Chapter 1: High level overview of concepts.
Chapter 2: Introduction to OpenGL
Chapter 3: More OpenGL
- Display Lists
- Double Buffering
Chapter 4: Geometric Objects and Transformations
- Scalars, Points and Vectors - what are they and what operations are allowed between them?
- Vectors: representation, length, addition, scalar multiplication,
dot products, cross products.
- Matrix Operations: multiplication, addition, determinants, transpose, inverse (of standard
transformations such as rotations, translations,scale), identity.
- 2D Transformations: Translation, scaling, rotation, shear, reflection, projection.
See
web notes.
- 3D Transformations: Translation, scaling, rotation, shear, reflection, projection.
- Composition of transformations.
- Homogeneous coordinates. What are they, why are they used?
- 3D Transformations in opengl using the ModelView Matrix.
- Homework problems: Word document.
- 3D Rendering
Pipeline - what is the sequence of operations and transformations.
Terminology:
